AirsoftParts Air Seal Set for MP5 AEG
AirsoftParts air seal set for MP5 combines four important AEG air seal components in one cost-effective set. It includes a POM piston head, silent cylinder head, ported cylinder and a 20.4 mm nozzle. This combination is designed for MP5-type AEGs and provides a practical solution when replacing a major part of the air seal system or building a new configuration. The ported cylinder has a reduced usable air volume compared with a full cylinder, which suits the shorter inner barrels typical of the MP5 series. The piston head, cylinder head and nozzle form interconnected parts of the compression system, where proper air sealing and correct matching with the specific gun are essential for proper operation. In particular, the 20.4 mm nozzle length should be compared with the original part before installation, as different MP5 variants and manufacturers may use different air seal component dimensions.
Key Features
Four Air Seal Components in One Set
The set combines a piston head, cylinder head, cylinder and nozzle, so the main interconnected air seal components do not need to be purchased separately.
POM Piston Head
The set includes a POM piston head that moves inside the cylinder and uses its seal to generate the required air pressure as the piston moves.
Silent Cylinder Head
The silent cylinder head closes the front section of the compression chamber, and its design also helps dampen the mechanical impact of the piston assembly.
Ported Cylinder
The ported cylinder has a reduced usable working volume compared with a full cylinder, allowing the amount of compressed air to be matched to configurations with shorter inner barrels.
20.4 mm Nozzle
The set includes a 20.4 mm nozzle. Before installation, it is advisable to verify the required length for the specific combination of gearbox and hop-up chamber used in the MP5.

Frequently Asked Questions (FAQ)
Is the Set Designed for All MP5-Type AEGs?
The set is designed by the manufacturer for MP5-type AEGs, but specific compatibility depends on the design of the particular model. It is especially important to verify the 20.4 mm nozzle length and the compatibility of the other components with the gearbox and hop-up chamber used.
What Does the Set Include?
The package includes a POM piston head, silent cylinder head, ported cylinder and 20.4 mm nozzle. These are four interconnected components of the AEG air seal system.
Why Does the MP5 Set Include a Ported Cylinder?
The port in the cylinder reduces its usable working volume compared with a full cylinder. This solution is used for configurations with shorter inner barrels where the full volume of a non-ported cylinder is not required.
Why Is It Important to Check the Nozzle Length?
The correct nozzle length affects how it works with the hop-up chamber and hop-up bucking. This set uses a 20.4 mm nozzle, so its dimensions should be compared with the original part or the requirements of the specific gun before purchase.
